  1. 10
  2. 11
  3. 15
  4. 8

Correct answer and explanation

Correct answer: 11

Explanation: āœ… Correct Answer: B. 11 šŸ“š Explanation: Using the formula for work (W1/M1D1 = W2/M2D2), we get 33 / (15 * 11) = 22 / (10 * D). This simplifies to 1/5 = 22 / (10 * D). Solving for D gives 10D = 110, which means D = 11. Therefore, it will take exactly 11 days for 10 ploughs to finish the work on 22 bighas.
